create an equation from the model that describes the relationship between the weights on each side of the scale
The algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.
How to Create an Algebraic Equation?Using the weights on each side of the scale, we can create an algebraic equation that describes it.
Assume each weigh on the scale represents each side of an algebraic equation.
On left side, we can express the weights as: 2y + 3
On the right side, we can express the weight as: 4y + 2
Thus, expressing the relationship of the weights, we would have:
2y + 3 = 4y + 2
Thus, the algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.

Elena and Diego each wrote equations to represent these diagrams. For each diagram decide which equation you agree with, and solve it. You can assume that angles that look like right angles are indeed right angles.
Elena: X=35
Diego: X+35=180
Answer: Diego is correct, and X = 145
Step-by-step explanation:
The line that 35* and x* rest on must equal 180*. Elena cannot be right if we assume this, as 35 + 35 = 70. We must then move onto Diego's formula.
[tex]X + 35 = 180[/tex]
[tex]180 - 35 = X[/tex]
[tex]X = 145[/tex]
Solving this, we would subtract 35 from 180, leaving us with 145*. This must be correct as the solution would give us the total we need.

7 rationals and irrationals prove that the product of a non-zero rational number and an irrational number is irrational.
Let x be a rational number and y be an irrational number. This is the correct choice.
Allow xy=a.
Suppose an is a rational being.
A can be stated as q p since it is rational, where p and q are both integers.
Let x = n m, where n and m are both integers.
Then, xy=a
n \smy \s \s = \sq \sp \s \s .
When we cross multiply, we obtain,
⇒y= qm \spn \s \s .
Pn and qm are currently integers.
Consequently, qm pn is a rational number.
Y, however, is illogical.
Consequently, our assumption is unfounded.
Therefore, an irrational number is always the result of adding a non-zero rational number to an irrational number.

9+8n≤1 please help me with this
Answer:
n ≤ -1
Step-by-step explanation:
Inequality is a concept that refers to the unequal distribution of resources, opportunities, or status among individuals or groups. It can be measured in a number of ways, including income inequality, wealth inequality, and educational inequality.
For the Question:
Let's solve for 'n':
Given inequality:
[tex]\sf 9 + 8n \leq 1[/tex]
Subtract 9 from both sides:
[tex]\sf 9 + 8n -9 \leq 1 -9[/tex]
[tex]\sf 8n \leq -8[/tex]
Divide both sides by 8 (remember, since you're dividing by a negative number, the inequality sign flips):
[tex]\sf \dfrac{8n}{8} \leq \dfrac{-8}{8}[/tex]
n ≤ -1
So, the solution for 'n' that satisfies the inequality is n ≤ -1.

If f (x) = 2 x + 5 and three-halves are inverse functions of each other and StartFraction 41 Over 8 EndFraction,
The value of the inverse function f⁻¹(8) is [tex]\frac{3}{2}[/tex] .
An inverse function in mathematics is a function that "undoes" another function.
In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹ .To calculate the inverse of the function f (x) = 2 x + 5 we simply write the function in the form y = 2x + 5 .
Now we solve the equation for x.
∴ y = 2x + 5
or, 2x = y-5
or, x = (y-5)/2
Hence the inverse of the function is given as:
f⁻¹ (x) = (x - 5 ) / 2
Now we have to find the value of f⁻¹ (8).
f⁻¹ (8) = (8-5) / 2
or, f⁻¹ (8) = 3 / 2
Hence the value of f⁻¹ (8) is 3 / 2 .

The new coordinates of the image A' will be (-5, -9).
Here, we are given a point on the cartesian plane- A (-5, 9)
It is reflected along the x axis to form a new point A'
Originally, we can see that the point A will be in the 2nd quadrant as x is negative and y is positive.
Now, when it is reflected across the x axis, the point will shift from the 2nd quadrant to the 3rd quadrant.
In the third quadrant, both x and y values are negative. Thus the coordinates of the reflected point A' will become (-5, -9).
Note that the absolute values of the point will not change when it is reflected. It is only the signs that change.

4 cards are drawn at random from a standard deck. find the probability that all the cards are hearts. find the probability that all the cards are face cards. note: face cards are kings, queens, and jacks. find the probability that all the cards are even. (consider aces to be 1, jacks to be 11, queens to be 12, and kings to be 13)
The probability that all the 4 cards are
1) hearts = 0.0026
2) face cards = 0.0018
3) even cards = 0.0179
In a standard deck of cards, we have:
Total number of cards= 52
1) The probability that all the cards are hearts.
In a standard deck of cards, we have:
the number of Hearts = 13
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are hearts is:
P1 = 13/52 × 12/51 × 11/50 × 10/49
P1 = 0.25 × 0.2353 × 0.22 × 0.2041
P1 = 0.0026
2) The probability that all the cards are face cards.
In a standard deck of cards, we have:
Face card = 12
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are face cards.
P2 = 12/52 × 11/51 × 10/50 × 9/49
P2 = 0.2308 × 0.2157 × 0.2 × 0.1837
P2 = 0.0018
3) The probability that all the cards are even.
In a standard deck of cards, we have:
Even cards = 20
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are even.is:
P3 = 20/52 × 19/51 × 18/50 × 17/49
P3 = 0.3846 × 0.3725 × 0.36 × 0.3469
P3 = 0.0179
Hence, the probability that all the 4 cards are even is 0.0179

Describe the similarities and differences between finding the slope of a linear equation from a graph that has x and y scales that are 1:1, and from a graph that has x and y scales that are not 1:1 (say your x and y scales are 2, 4, 6).
Using the concept of the slope of a linear function, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in the graph of a function, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

d) Monte collected 5 more than Cecil.
How many gems didCecil collect?
How many gems did Alice collect?
How many gems did Jaime collect?
How many gems did amir collect
How many gems did Monte collect
Using a system of equations, the amounts of gems collected by each member is are given as follows:
Cecil: 13Alice: 40Jaime: 108Amir: 3Monte: 18.What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of gems collected by Cecil.Variable y: Number of gems collected by Alice.Variable z: Number of gems collected by Jaime.Variable t: Number of gems collected by Amir.Variable w: Number of gems collected by Monte.They collected a total of 182 gems, hence:
x + y + z + t + w = 182.
Alice collected 1 more than 3 times what Cecil did, hence:
y = 3x + 1.
Jaime collected 12 less than 3 times what Alice did, hence:
z = 3y - 12 = 3(3x + 1) - 12 = 9x - 9.
Amir collected 10 less than Cecil, hence:
t = x - 10.
Monte collected 5 more than Cecil, hence:
w = x + 5.
Replacing everything in the first equation, we can solve for x as follows:
x + y + z + t + w = 182.
x + 3x + 1 + 9x - 9 + x - 10 + x + 5 = 182.
15x = 195
x = 195/15
x = 13.
Hence the other variables are:
y = 3(13) + 1 = 40.z = 9x - 9 = 9(13) - 9 = 108.t = x - 10 = 13 - 10 = 3.w = x + 5 = 13 + 5 = 18.Thus the amounts of gems collected by each member is are given as follows:
